Unable to restore old session even after following all instructions I could find
I was using Firefox when suddenly it was no longer there. When I clicked on the icon, it reopened, with all my bookmarks and history, but no tabs! I stupidly shut it down again. The forums all said to just go to History > Restore Previous Session, only there was no such option in History. I tried to do a Windows System Restore to several days ago, but it keeps failing and suggesting that I turn off my anti-virus, which I have. Further reading in the Mozilla forums said to take an old upgrade.jsonlz4-20240618110440 (or whatever date) file from the sessionstore-backups folder and move it into the main profile folder and rename it sessionstore.jsonlz4 (I can no longer use the recovery.jsonlz or previous.jsonlz files because I'd stupidly shut down Firefox after it had loaded with no tabs). I have done this and restarted Firefox, but still get no tabs. That file is huge (22MB) and I've examined its contents and can verify that the tabs are there. So why isn't Firefox reading it when I run it and displaying my tabs? I did see that other people on the forums had this problem but I didn't see a solution. One remote possibility may be that my current version is 127.0.2 (64-bit), while the upgrade.jzonlz... file was clearly generated as a snapshot of when the version was 127.0.1. What can I do to restore my tabs, in light of the fact that I don't have a recovery.jsonlz or previous.jsonlz file with the tabs any more and Windows System Restore is unable to restore my system to several days ago?

CANCEL THIS WHOLE QUERY! After leaving the computer turned on overnight, I came back in the morning, discovered that the old upgrade.jsonlz4 file I had put in the profile and renamed sessionstore.jsonlz4 had mysteriously disappeared for some reason, so I did it again, and suddenly it DID work, and all my tabs have been miraculously restored to the condition they were in at of the date that upgrade.jsonlz4 file had been created. I have no idea why this didn't work yesterday but did work today, but the important thing is that it did work and I can continue life as I know it. Thank you for your time, cor-el.

Did you possibly cancel a Primary Password prompt when Firefox started?
I assume you placed the upgrade.jsonlz4 file as sessionstore.jsonlz4 at the top level in the Firefox profile folder?
Sorry, I don't even know what a Primary Password prompt is, but I'm pretty sure I did not cancel it when I started Firefox, because I have never gotten any password prompts when starting Firefox.
I also don't know what you mean by placing the file "at the top level" in the Firefox profile folder. I am unaware of any levels in the folder. I copied the upgrade.jsonlz4 file that was in the sessionstore-backups folder into the c:\Users\<my username>\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default-#############\ folder (where the xxx and ### stand for the actual name of the default profile folder), then renamed the existing sessionstore.jsonlz4 file there to something else, and renamed the upgrade.jsonlz4 file as sessionstore.jsonlz4.
